For decades, introversion was looked at as something to overcome, almost like an illness. The way to win in life was through charisma, outspokenness, and self-promotion.

Even now, in an increasingly noisy world, introverts may feel added pressure to take one of two paths: force themselves into more extroverted behavior, or become even more reserved and shrink back to themselves.

My guest Susan Cain says both paths are wrong and in fact, rob the world of the unique contributions introverts make when they choose to be true to themselves.
